Did you have to use a lot of windage to zero the scope?

You may be canting(rotating) the rifle when you look under the scope. You might try removing the scope and sighting in again.

I would take the rifle to a gunsmith or a machinist who can eyeball the barrel as it may be bent.

You can sight in a bent barrel, but, the windage will only be right for that distance.

Bad barrels, machining, and assembly mistakes happen, CVA ought to make good on it if that's the case.

Good Luck
